Question about voltas and repeats

[Lucas Cavalcanti]

Hello. I've been thinking about Lilypond's usage on parts: for one musician
(for example, the singer singing the melody) I'd like to give them a score
containing voltas using the repeat and volta commands; for another musician
(for example, the drummer) I'd like to give them a score with no repeats
and voltas. I know that if I'd like to create a full-band score (i.e a
grid) I can use the \unfoldRepeats at every variable, creating one straight
through score.

However, is it possible to create something like a "Tempo Map" of sorts?
Like a part/variable that gives instructions to the master grid to create
repeats and voltas without the need to create new parts?

My objective is to figure out a way to create independent grid scores from
musician part scores. To give a singer one straight, 6 pages score, to give
a drummer a 1 page score and to give the conductor a 4 page score.
Is that possible?

Best regards, Lucas.
